Definitions
- the present invention relates to wood and iron golf clubs and, more particularly, to means for reinforcing wood and iron golf club heads.
- woods pertains to a family of golf clubs having shafts of longer length, used primarily for tee and fairway shots where considerable distance is the object.
- "Iron” clubs are those of shorter length, generally employed for shorter distances.
- woods with club heads made of wood materials are being superceded by heads made of metal or of composite graphite or other materials.
- Metallic heads are usually hollow in construction, to produce a head with volume large enough for practical use. Because the density of metallic materials is so high, solid club heads of adequate volume are prohibitively heavy. While most composite graphite club heads to date have been of solid construction, recent designs for these club heads have also incorporated hollow interiors. In any case, composite graphite heads generally include separately attached sole plates, usually made of steel, aluminum or brass.
- iron club heads In the case of iron club heads, these club heads have traditionally been solid. However, hollow iron club heads have been available for about two decades.
- Hollow woods and irons have met with several difficulties.
- the striking faces of the heads can not withstand impact forces over time, resulting in denting or face collapse.
- the club head distorts excessively during impact with the ball, due to compressive forces.
- concentration of club head weight at the face necessitates making the rest of the club head with thinner walls to keep the club head at the desired weight. Crumpling and fracturing of these thinner wall surfaces has occurred at undesirable rates.
- Injection molded composite graphite heads have tended to be too soft for the application, yielding a poor energy transfer from head to ball.
- Harder material inserts, located in the striking face at the impact zone, have been a general remedy, but overall head distortion during head-ball collisions is still high.
- Compression molded composite graphite solid heads have tended to resist impact forces well, but the comparative cost of compression molded heads is too high.
- U.S. Pat. Nos. 4,076,254; 5,000,454; 4,535,990; 4,313,607; 4,756,534, 4,681,321; and 1,658,581 generally disclose a support member in the club head interior extending from the interior side of the club striking face to the rear of the club.
- Other designs utilize special alloys, including cobalt, to improve club head strength. None of the above utilize the structural properties of triangulation to advantageously resist deformation and enlarge the sweet spot of the striking face.
- a golf club head having a striking plate with an outer side and an interior side and a tail spaced from the interior side of the striking plate.
- a sole extends between the striking plate and the tail, and a plurality of struts engage the interior side of the striking plate and extend toward the tail. The struts converge to form an apex adjacent the tail of the club head.
- the struts are interconnected at the interior side of the striking plate by a plurality of base rods.
- the base rods define a support cell directly behind the striking plate, which may be in the shape of a polygon.
- the base rods define an equilateral triangle so that the base rods in cooperation with the struts form a triangular, pyramid-shaped truss, also known as a "Modified Fink Truss".
- a pyramid base engages the interior side of the striking plate with a pyramid point adjacent the tail.
- the truss employs the properties of triangulation to resist deformation and distortion of the striking plate.
- FIG. 1 is a perspective view, partially broken away, of a wood golf club having a hollow head with a pyramid truss according to the present invention located therein;
- FIG. 2 is a sectional view taken along lines 2--2 of FIG. 1;
- FIG. 3 is a front view of a club head showing in phantom a truss according to the present invention positioned behind the striking plate of the club;
- FIG. 4 is a perspective view showing a truss according to the present invention.
- FIG. 5 is a perspective view of the truss of FIG. 4, including a pair of interior brace members;
- FIG. 6 is a graphic illustration of force versus time for the impact of a wood club head, particularly a "driver”, with a golf ball at club head speed of 100 mph;
- FIG. 7 is a front elevation view of a golf club having a club head according to the present invention.
- FIGS. 1-3 show a wood club head 10 incorporating the present invention.
- Club head 10 has a hosel 12 which receives a shaft 14.
- the club head also has a toe 11 spaced from the hosel 12 and a heel 13 adjacent hosel 12.
- a grip 16 is located on an end of the shaft opposite club head 10 for grasping by the golfer.
- club head 10 has a striking plate 18 having an outer side or “face” 20 and an interior side 22.
- Club head 10 also has a tail 24 spaced from the interior side 22 of striking plate 18, and a sole 26 having an inner side 28 and an outer side 30, extends between striking plate 18 and tail 24.
- a top cover 32 extends above sole 26, and the top cover, sole, striking plate and tail cooperate to define a hollow interior 34 for club head 10.
- Truss 36 includes three struts 38 which engage the interior side 22 of striking plate 18 and extend toward tail 24. At least two of the struts 38, and preferably all three, converge to form an apex 40 adjacent tail 24.
- the apex 40 may be either blunt or pointed and preferably engages tail 24.
- the truss 36 also includes three base rods 42 which engage the interior side 22 of face plate 18.
- the base rods interconnect the struts 38 at their points of engagement with striking plate 18 to define a support cell 44 behind the striking plate.
- the base rods are preferably fixed to the interior side 22 of the striking plate, such as by welding. It is generally preferred that the support cell 44 is in the shape of a polygon, most preferably an equilateral triangle. However, in some applications the support cell may be circular or otherwise.
- the struts 38 and base rods 42 cooperate to define the truss 36.
- the base rods 42 define a pyramid base while the apex 40 defines a pyramid point adjacent the tail 24.
- the struts 38 and base rods 42 may be tubular or they may be solid, depending on the type of materials used to form the club head 10, the shape and design of the club head and the thicknesses of the various club head walls 18, 24, 26, 32.
- two of the struts 38 are engaged on the inner side 28 of sole 26, such as by welding. This provides added support and rigidity to the striking plate 18.
- FIG. 5 A second embodiment of the truss 36 is shown in FIG. 5.
- This truss includes two interior brace members 46, each extending between two struts 38 intermediate the striking plate 18 and the tail 24.
- the interior brace members 46 extend from the two struts 38 which are adjacent the sole 26 at their points of engagement with the striking plate 18 upward to the third strut 38 intermediate its point of engagement with striking plate 18 and the tail 24.
- This truss design is useful in club heads requiring thinner walls, such as "jumbo" wood club heads, which are oversized. This provides support for striking plate 18 while maintaining proper club head weight. Striking plate 18 can thus be thinner to accommodate jumbo club head design criteria.
- the struts and base rods are welded, first to the walls 18, 24, 26, 32 at their respective interior locations and then to one another during final assembly of the head.
- the truss 36 will first be completely assembled and firmly attached to the inner side 28 of sole 26. It is anticipated that the composite graphite head would then be molded about this structure to ensure firm bracing of the several walls 18, 24, 26 and 32.
- the truss facilitates using relatively inexpensive injection molding to accomplish this objective. As described below, the truss adds structural strength to the club head heretofore unobtainable with injection molding.
- FIG. 6 illustrates the variation of force with time between a driver club head and a golf ball.
- the driver is used to hit the ball the greatest distance possible by the golfer.
- the force may be measured at varying club head speeds through transducers wired to three club head locations. The measurements may be recorded on an oscilloscope. To confirm the measurements, the force may be calculated utilizing the following formula: ##EQU1##
- the force transmitted to a golf ball by a stronger golfer is on the order of 2600 pounds.
- the club head 10 receives the same magnitude of force from the ball.
- Club heads for drivers typically weigh between 7 and 71/2 ounces. If the striking plate 18 is made of stainless steel, for example “431” or “17-4", the striking plate must be sufficiently thick or it will collapse. These forces on impact may also compress the entire club head 10, producing an inefficient energy transfer from head to ball. The total time during collision is so short that the deformed head cannot restore its shape before the ball is already in flight. Off center hits exacerbate these problems. The club head will twist around its center of gravity and the ball will then be directed off the target line due in part to the well-known gear effect.
- the truss 36 of the present invention employs the structural properties of triangulation to resist this deformation and distortion.
- the triangular pyramid formed by the struts 38 extending from behind striking plate 18 to the tail 24 will brace against the forces discussed above.
- the truss 36 will retard distortion and twisting due to the fact that the base rods 42, which define support cell 44, support the interior side 22 of striking plate 18 and enlarge the "sweet spot" hitting zone of the striking plate. Forces applied to the striking plate are thus transmitted through struts 38 to the rear of club head 10 at the apex 40.
- the truss 36 resists deformation and distortion of the striking plate 18, maximizing the efficiency of energy transfer from club head 10 to the golf ball and minimizing problems related to off center hits on the striking plate.
